Definitions

  • ARTYOM LOMAYEV "Performance Comparison of Dual Carrier and Regular Modulations for SU-MIMO in 11 ay"
  • XP068119471 discloses Dual Carrier Modulations (DCMs) defined for the legacy llad OFDM PHY and regular BPSK and QPSK modulations.
  • channels in the embodiments of this application are four channels obtained by dividing a free-of-charge 60 GHz frequency band, and are corresponding to sequence numbers 1, 2, 3, and 4 in FIG 1 .
  • the four channels each have a bandwidth of 2.16 GHz, and central frequencies corresponding to the four channels are respectively 58.320 GHz, 60.480 GHz, 62.640 GHz, and 64.800 GHz.
  • N and M are integers greater than or equal to 2.
  • N is introduced to indicate a plurality of high-order modulated signals or indicate a plurality of subcarriers, and the n th high-order modulated signal is transmitted on the n th subcarrier.
  • M is introduced to indicate a plurality of channels, and the N subcarriers are the subcarriers on the frequency domain resources of the M channels.
  • a relationship between the quantity N of subcarriers and the quantity M of channels may be selected with reference to a specific situation. For example, there may be four subcarriers on two channels or nine subcarriers on three channels. This is not limited.
  • the four high-order modulated signals are transmitted on the four subcarriers of the two channels. This can improve efficiency of a diversity gain.
  • FIG 17 is a schematic diagram of an example of three-channel aggregation according to an embodiment of this application.
  • a specific transmission solution of high-order modulated signals is: transmitting a first high-order modulated signal x 1 on a first subcarrier of a first channel, transmitting a second high-order modulated signal x 2 on a second subcarrier of a second channel, transmitting a third high-order modulated signal x 3 on a third subcarrier of a third channel, transmitting a fourth high-order modulated signal x 4 on a fourth subcarrier of the first channel, transmitting a fifth high-order modulated signal x 5 on a fifth subcarrier of the second channel, transmitting a sixth high-order modulated signal x 6 on a sixth subcarrier of the third channel, transmitting a seventh high-order modulated signal x 7 on a seventh subcarrier of the first channel, transmitting an eighth high-order modulated signal x 8 on an eighth
  • the plurality of low-order modulated signals are combined into the N high-order modulated signals; and the N high-order modulated signals are transmitted on the N subcarriers, where the N subcarriers are the subcarriers on the frequency domain resources of the M channels.
  • the N modulated signals are transmitted on the N subcarriers of a plurality of subbands. This can improve efficiency of a diversity gain.
  • the computer software product is stored in a storage medium, and includes several instructions for instructing a computer device (which may be a personal computer, a server, a network device, or the like) to perform all or some of the steps of the methods described in the embodiments of this application.
  • the storage medium includes any medium that can store program code, such as a USB flash drive, a removable hard disk, a read-only memory (Read-Only Memory, ROM), a random access memory RAM, a magnetic disk, or an optical disc.
